Wanting to be able to just turn it off and relax etc is a common desire with stress/anxiety/and PTSD. I think your choice is a good one, IMHO, nothing wrong with it, and it is actually a more natural way that human beings were designed to relieve stress anyway, that has a lot to do with how we developed into what we are now too.

I also think just venting here is good for you too because others here can really relate.

I hope you have a nice weekend riding your bike in whatever way you enjoy it best.
